A von Mises-Fisher Distribution for the Orbital Poles of the Plutinos
Ian C. Matheson, Renu Malhotra, James T. Keane
Small solar system bodies have widely dispersed orbital poles, posing challenges to dynamical models of solar system origin and evolution. To characterize the orbit pole distributi…
Large-scale cryovolcanic resurfacing on Pluto
Kelsi N. Singer, Oliver L. White, Bernard Schmitt +22
The New Horizons spacecraft returned images and compositional data showing that terrains on Pluto span a variety of ages, ranging from relatively ancient, heavily cratered areas to…
A Predicted Dearth of Majority Hypervolatile Ices in Oort Cloud Comets
C. M. Lisse, G. R. Gladstone, L. A. Young +30
We present new, ice species-specific New Horizons/Alice upper gas coma production limits from the 01 Jan 2019 MU69/Arrokoth flyby of Gladstone et al. (2021) and use them to make pr…
A Near Surface Temperature Model of Arrokoth
O. M. Umurhan, W. M. Grundy, M. K. Bird +19
A near surface thermal model for Arrokoth is developed based on the recently released facet model of the body. This thermal solution takes into account Arrokoth's surface re…
New Constraints on Pluto's Sputnik Planitia Ice Sheet from a Coupled Reorientation-Climate Model
Perianne E. Johnson, James T. Keane, Leslie A. Young +1
We present a coupled reorientation and climate model, to understand how true polar wander (TPW) and atmospheric condensation worked together to create the Sputnik Planitia (SP) ice…
A Statistical Review of Light Curves and the Prevalence of Contact Binaries in the Kuiper Belt
Mark R. Showalter, Susan D. Benecchi, Marc W. Buie +19
We investigate what can be learned about a population of distant KBOs by studying the statistical properties of their light curves. Whereas others have successfully inferred the pr…
The science case for spacecraft exploration of the Uranian satellites: Candidate ocean worlds in an ice giant system
Richard J. Cartwright, Chloe B. Beddingfield, Tom A. Nordheim +15
The 27 satellites of Uranus are enigmatic, with dark surfaces coated by material that could be rich in organics. Voyager 2 imaged the southern hemispheres of Uranus' five largest '…
On the Origin and Thermal Stability of Arrokoths and Plutos Ices
C. M. Lisse, L. A. Young, D. P. Cruikshank +30
We discuss in a thermodynamic, geologically empirical way the long-term nature of the stable majority ices that could be present in Kuiper Belt Object 2014 MU69 after its 4.6 Gyr r…
Initial results from the New Horizons exploration of 2014 MU69, a small Kuiper Belt Object
S. A. Stern, H. A. Weaver, J. R. Spencer +202
The Kuiper Belt is a distant region of the Solar System. On 1 January 2019, the New Horizons spacecraft flew close to (486958) 2014 MU69, a Cold Classical Kuiper Belt Object, a cla…
The Geology and Geophysics of Kuiper Belt Object (486958) Arrokoth
J. R. Spencer, S. A. Stern, J. M. Moore +75
The Cold Classical Kuiper Belt, a class of small bodies in undisturbed orbits beyond Neptune, are primitive objects preserving information about Solar System formation. The New Hor…
The solar nebula origin of (486958) Arrokoth, a primordial contact binary in the Kuiper belt
W. B. McKinnon, D. C. Richardson, J. C. Marohnic +26
The New Horizons spacecraft's encounter with the cold classical Kuiper belt object (486958) Arrokoth (formerly 2014 MU69) revealed a contact-binary planetesimal. We investigate how…
Photometry of Kuiper Belt Object (486958) Arrokoth from New Horizons LORRI
Jason D. Hofgartner, Bonnie J. Buratti, Susan D. Benecchi +14
On January 1st 2019, the New Horizons spacecraft flew by the classical Kuiper belt object (486958) Arrokoth (provisionally designated 2014 MU69), possibly the most primitive object…
Color, Composition, and Thermal Environment of Kuiper Belt Object (486958) Arrokoth
W. M. Grundy, M. K. Bird, D. T. Britt +46
The outer Solar System object (486958) Arrokoth (provisional designation 2014 MU) has been largely undisturbed since its formation. We study its surface composition using da…
Plutos Far Side
S. A. Stern, O. L. White, P. J. McGovern +11
The New Horizons spacecraft provided near global observations of Pluto that far exceed the resolution of Earth-based data sets. Most Pluto New Horizons analysis hitherto has focuse…
Evidence for Lunar True Polar Wander, and a Past Low-Eccentricity, Synchronous Lunar Orbit
James Tuttle Keane, Isamu Matsuyama
As first noted 200 years ago by Laplace, the Moon's rotational and tidal bulges are significantly larger than expected, given the Moon's present orbital and rotational state. This…
Herschel evidence for disk flattening or gas depletion in transitional disks
J. T. Keane, I. Pascucci, C. Espaillat +6
Transitional disks are protoplanetary disks characterized by reduced near- and mid-infrared emission with respect to full disks. This characteristic spectral energy distribution in…
